Sticky prints with new resin

[Grassic87]

Just started resin printing with a 2023 NovaForm DLP printer and used a “fast cure” resin I got nearby. The prints look okay but still feel sticky after 10 minutes under my UV light. Not sure if it’s the resin or my light setup. Has anyone had this happen with other brands?

Clean the prints well first, you gotta make sure you're doing that and try rotating them under the light for a more even cure. A stronger or more enclosed curing setup can make a big difference too

Could be the resin itself like I’ve had batches that just never fully hardened no matter what. If you’ve got any older resin left, try curing a test cube from both side by side. If only the new one stays sticky, it’s probably a formulation issue or shelf life problem. Some of those “fast cure” types trade hardness for speed.
